APPLICATION
TRIBASTIC CALCIUM PHOSPHATE
Tribasic calcium phosphate (TCF) (triple-substituted calcium phosphate, Ñà3(ÐÎ4)2) GOST 23999-80 – is the most widely spread calcium and phosphorous additive traditionally used in practice of animal breeding. For many years tribasic calcium phosphate was the only widely spread fodder phosphate. Such traditions concerning use of TCF allow some specialists even at the present time to identify term “fodder phosphates” with only one type of them - tribasic calcium phosphate.
Fodder phosphate TCF represents grey or brown with green shadow, creme or light-yellow, white with grey shadow amorphous powder. Such difference in colours is a result of different chemical composition of initial material of independent deposits of apatites which are used for production of tribasic calcium phosphate. Final product includes about 93 % chemically clean tribasic calcium phosphate. Depending on content
of macroelements there is fodder calcium phosphate of two sorts: high sort, 1st sort.
